All vehicles should have easy to replace external fuel filters, hated to see that go away.

Good advice, Over the years I have harvested many GM parts from junk yards building past cars, trucks and projects. Surveying the donor vehicle is the key, there is no general rule of mileage. (now if it has 500k that's a different story) My guess I grabbed is over 2 dozen engines junkyard diving, getting LS, Gen2/3 and a few big blocks and a couple 455 Pontiac engines along the way. Bottom line was the total vehicle assessment was the deciding factory and gave me insight if I should pursue or skip the part I was interested in.

I have seen some with as little as 50k that were toasted and total crap and other with close to 300k that were perfect for a light rebuild, some I was able to just hone up put in some new rings, .001 oversized bearings, new cam, lifters, pumps and they ran like new stuff.
Same rules apply to trans, xfer cases and diffs.

GM for the most part did the right thing with the H2 most of the drive train parts were gotten for the GM HD 2500 truck line (with the exception of the trans) with good care and staying on top of fluid changes all around I would not think twice purchasing a clean one with 225k or not.
If you find a nice clean one consider spending a few bucks for a comprehensive review at a GM dealership. They can check the systems, verify codes and see if something that might be lurking you can't see or don't have tools to check.

Some things just wear out even with good care and reasonable use. A 200k plus H2 will probably be a candidate for ball joints, steering gear, tie rod ends, pitman and idler arms, front half shafts/boots. Power steering pump and Hydroboost unit/master cylinder, and a trans if one has not already been replaced. Other haunting items could be radiator, AC blending doors, misc electronics and so on. And the a biggie, did it come from the snow belt.

An H2 can bring you much joy buying the right one or major misery if you get the wrong one. Do your homework, take your time and look at a bunch of them, know exactly what your willing to spend and time and effort you wish to put into it and keep in mind the vehicle you are looking at is at least 14 years out of production and certain replacement parts can be a challenge to find. Personally I'm on my third and if god forbid it got destroyed I would look for another in a heartbeat, they are that special.

There are past posts also that are great to research because this seems to be a great question for “new” Hummer h2 buyers.

mechanicals , front end, etc are all common parts. You can restore mechanicals easily (again budget) - body, rust, trashed interiors are very hard to replace…

my 2 cents. On my 4th H2 - only vehicle I have ever owned that I love to own and drive. Nothing else has kept my attention, including many exotics - period.

just personal preference- I would guess even if you left $7500 you could make the mechanicals as new. What else can you have $30k in be like new and people still come up and compliment … don’t rush. Take time and find a clean rust free example. Patience. You will find a diamond.

so - to me high miles may not be a deal breaker if the H2 is in stellar cosmetics.
